MEASURlNG-VESSEL.

SPECIFICATION forming part of Letters Patent No. 373.537, dated November22, 1887.

Application filed February 3, 1887. Serial No. 226.418. (No model.)Patented in England December 8,1885, No. 15,065; in Germany September19, 1886, No. 39,047, and in France September 21,1886, No.178,654.

To all whom it may concern.-

Be it known that I, GEORGE HENRY SMITH, a subject of the Queen of greatBritain, residing at London, England, have invented new and usefulImprovements in the Construction of Taps for Measuring and Registeringthe Quantity of Liquid Passed Therethrough, (for which I have obtainedpatents in the follow ing countries-namely, Great Britain, No. 15,065,dated December 8, 1885; Germany, No. 39,047, dated September 19, 1886,and in France,N0. 178, &, dated September 21, 1886,) of which thefollowing is a specification.

My improvements consist in so constructing measuring-taps that theminimum risk of derangement and liability to leak is obtained.

In order to carry out my invention I provide a cylinder made of anysuitable materialsuch as brass, pottery, or glass-the capacity of suchcylinder being equivalent (minus a slight portion consisting of othernecessary parts) to the maximum quantity the tap is to measure. Thebottom of the cylinder I construct of a suitable shape to form what mayhe termed the cylinder base cap, and also to contain a two-way cone-cockwhose axis runs in avertical line with the cylinder. This cone at thebottom part is hollow and extends outward below the casing, thus formingthe spout for the liquid drawn off. Outside this spout I place a castingof a suitable shape,which serves the double purpose of a washer andhandle to turn the tap by. The bottom part or cover of the cylinder isformed with one of the connections to the barrel or vessel containingthe liquid to be measured. Extending up from the cylinder base-cap andconnected to suitable ports in the casing of the two-way conecook Iattach pipes extending to any desired height into the cylinder. In theplug of this cone-cock passages are set apart the same distance as theports referred to in the casing. The plug or cone-cock extends upward tothe top of the cylinder; but the size of the plug may here be reduced.This extension of the plug engages into a one-way cone-cock in the topof the top cylinder cover. Extending from the casing of the topcone-cockisa pipe, forming the other connection of the barrel referred to. Airholes are made in the conecock casing at similar distances apart towhich the ports are in the lower casing. The plug of the top coneextends upward, and can be adapted to actuate an indicator or counter,which can be of any suitable construction.

In order to enable my invention to be fully understood, I will proceedto describethe same by reference to the accompanying drawings, in whichFigure 1 represents a front elevation, and Figs. 2 and 3 are verticaltransverse sections, of a tap for measuring and registering the quantityof liquid passed therethrough constructed according to my invention.Fig. 4is a plan of the same with the top cylinder-cover removed. Figs. 5and 6 are an elevation and a vertical section, respectively, of the plugof the upper cone-cock. Fig. 7 is a side elevation of the topcylinder'cover.

Similar letters in all the figures represent similar parts.

a is the cylinder, the. capacity of which is almost equivalent to themaximum quantity the tap is to measure.

b is the cylinder base-cap, and c is the twoway cone-cock in the same, dand 0 representing the ways or passages.

f is the hollow bottom part of the cone-cock 0, extending outward belowthe casing and forming the spout for the liquid drawn off.

9 is the casting. fixed to the outside of the spoutf, which castingserves as a washer and handle to turn the tap by.

h is a plate on the cylinder a, marked with suitable words, letters,figures,or the like, and serving to indicate the positions to which thehandle must be moved in order to draw off the required measuredquantities of liquid.

2' is the connection for the lower part of the barrel or vesselcontaining the liquid to be measured, the said connection being formedon the base-cap b of the cylinder a.

j and k are the pipes, extending up to any desired height within thecylinder from the base-cap b, and Z and m are the ports in the cap b, towhich the said pipes are connected, which cap forms the casing of thetwo-way conecock 0.

n is athird port in the casing-cover b. The passage d in the cone-cock acan, by moving ICO the handle 9, be brought into communication with anyone of the ports Z, m, and n. The two pipes j and 7c,of differentheight, with their port-s Z and m, allow only such portion of the liquidto be withdrawn from the cylinder (and thereby measured) as is containedin either of the spaces between the upper ends of the pipesj or k andthe top of the cylinder, while the port it allows of the whole of thecontents of the cylinder being withdrawn, and thereby measured.

and p are the passages in the cone-cock c,

- set apart the same distance as the ports Z and the way or passageformed therein, which is ,tion.

always in communication with the interior of the cylinder a.

t is a notch or groove in the cone-cock r, in which the upper end of therod q engages, whereby the cone-cock ris caused to rotate with the lowercone-cock, c.

u is the pipe extending from the casing s, and forming a connection withthe air-space in the barrel or vessel containing the liquid to bemeasured.

v, w, and-0c are the air-holes in the casing s of the cone-cock 1', madeat'distances apart corresponding to the ports 1, m, and n in the casingb of the lower cone-cock, c.

y is the upward extension of the cone-cock 7', which extension can beadapted to actuate an indicator or counter of suitable construc- (Notshown in the drawings.)

2 is the cover of the casing s, and b is a spring for keeping the cocksr and c in position, and at the same time allowing thema certain amountof ease in act-ion.

c is a ball-valve, which I sometimes find it advantageous to apply tothe pipe 10, as shown in the drawings, (or in any other suitableposition,) the ball being of material of a less specific gravity thanthe liquid to be measured, so that as the said liquid enters the pipe u,when the cylinder at has become full, the ball will float and close thepipe, and thereby prevent the liquid rising therein.

d d are stops for limiting the movement of the handle 9. v

The operation of the tap is as follows: The tap in its normal condition(that is to say,when it is in the position shown in Fig. 2) is closed,in which position the passage or way e in the lower two-way cone-cock,c, is in direct communication with the lower connection, z, from thebarrel or other vessel containing the supply of liquid to be measured,and the cylinder or chamber a will be filled from the said the air whichwasin the cylinder at being forced up this pipe by the liquid as itenters the cylinder. When the valve 0 is used, the liquid in rising willfloat the ball thereof, so as to close the valve and prevent the liquidrising any higher in the pipe a. To open the tap, in orderto draw off ameasured quantitysay, for

example, the smallest measured quantity of the liquid-the handle 9 ismoved from the position shown in Fig. 2 to that shown in Figs. 1 and3that is to say, it is brought opposite the first division on the plateh. As the handle g is moved into the said position, both the connectionsi and u from the barrel will be first simultaneously cut off asthepassages e and a will be brought against the faces of the casings band s, and then the outlet-passage d in the lower cone-cock, c, (whichpassage is connected to the hollow spout f,) will be brought incommunication with the first port, I, in the casing 12, the said portbeing connected to the longest pipe, j, in the cylinder a at the sametime the passage ain the top cone-cock, T, will be brought incommunication with the first opening, '0, in the casing s. The liquidnow beingin connection with the spoutfon the lower cone-cock, c, andalso with the outer air through the top cone-cock, r, it will run out ofthe cylinder (1 until the liquid comes to the level of the top of thefirst pipe, j, and the required measuredquantity of liquid will in thismanner have been drawn oft. The handleg is then moved back, so as tobring the cocks c and 0 into their former position, as shown in Fig. 2,and the cylinder a will again become full. If it be now required to drawoff the next largest measured quantity of liquid, the handle must bemoved opposite the second division on the plate h, when the passage atwill be brought in communication with the port m and pipe 7c, and thepassage a will be opposite the second air-opening, w, in the casing s,and the liquid will run out of the cylinder until it reaches the levelof the top ofthe pipe k. It will be obvious that the cylinder beingfull, if the handle g be moved from the position shown in Fig. 2t0 thethird division on the plate h, the whole of the contents of-the'cylinderwill be drawn off. It will thus-beobvious that according to the size ofthe cylinder (1, the numberof pipes and the various lengths of the same,any varying quantities may be drawn from one measure. It will also beobvious that the said pipes can be made telescopic, so as to allow oftheir being adjusted according to the quantity of liquid to be drawnoff.

I have not shown in the drawings an indi cator or counter applied to myimproved tap, as it will be obvious that this may be of any suitableconstruction, and it will be easily understood without furtherdescription in what manner the said indicator or counter can be operatedby the tap. Further, the said indicator or counter would notalways berequired, and in such cases I dispense with its use.

Having now particularly described and as certained the nature of my saidinvention and IIO in what manner the same is to be performed, I declarethat what I claim is- 1. In a tap for measuring the quantity of liquidpassed throughit, the combination,with a cylinder or vessel of knowncapacity provided with internal pipes of known suitable heights, of twococks connected to each other, so as to operate in unison, and inclosedby casings provided with ports or openings, whereby when theliquid-outlet is opened external air is simultaneously admitted to theinterior of said cylinder or vessel, substantially as set forth.

2. The cylinder or vessel provided with internal pipes of suitableheights, combined with two cocks connected to each other, so as to op-
